"High-efficiency motors and a larger capacity battery gives lets you enjoy up to 28 minutes of flying time with the Phantom 4 (without GPS active)" So what time does this translate to with GPS active?
Must be a big hit or they wouldn't give the 28mins (without active gps). I say not to expect more then 23-25 mins real world and that's if you completely deplete it and use it in slow mode.
where did you get this info! Actually if there is even a difference in a flight time it's only seconds.. however you are not going to get that time flying in the sport mode
